This update basically adds fixed packages for woody whose version turned out to be vulnerable as well.

For the old stable distribution (woody) this problem has been fixed in version 1.0.6-4woody5.

For the stable distribution (sarge) this problem has been fixed in version 1.4.1-1.sarge3.

For the unstable distribution (sid) this problem has been fixed in version 1.4.2.2-1.

We recommend that you upgrade your gnupg package.");
